a head portion supporting the floor panel; and
a connection portion inserted into the base portion and the head portion, wherein the connection portion is a height-adjustable thread,
wherein each of the four pedestal connection members connects the base portion with each of the pair of the first beam elements and the pair of the second beam elements by passing through each of the four base assemblies.
2. The support structure of claim 1 , wherein the first beam element includes a first body portion, and a first wing protruding outward from the first body portion,
the second beam element includes a second body portion, and a second wing protruding outward from the second body portion, and
any one of the first wing and the second wing is seated on a remaining one of the first wing and the second wing.
3. The support structure of claim 2 , wherein the first wing includes a first lower hole,
the second wing includes a second lower hole, and
the first wing and the second wing are connected to each other through a beam element connecting member inserted into the first lower hole and the second lower hole.
4. The support structure of claim 1 , wherein the base assembly includes:
a base nut with an opening, formed in the base portion; and
a base bolt rotatably coupled to the base nut, wherein
the base bolt includes a slot formed therein.
5. The support structure of claim 4 , wherein the first beam element includes a first upper hole,
the second beam element includes a second upper hole, and
the pedestal connection members is inserted into the first upper hole or the second upper hole by passing through the slot and the base nut.
6. The support structure of claim 4 , wherein the slot includes an opening linearly extending on the base bolt, and
the pedestal connection member is received in the slot such that the pedestal is movable within a range defined by a length of the openings of the slot, whereby the pedestal is movably seated on the top of the pair of first beam elements and the pair of second beam elements.
7. The support structure of claim 1 , wherein the head portion includes a seat guide portion protruding from an upper surface of the head portion by a predetermined thickness, and wherein the seat guide portion is affixed to the floor panel.
8. The support structure of claim 1 , further comprising:
stringers connected to the pedestal and extending in the first direction and the second direction, wherein
the stringers support the floor panel together with the pedestal.
9. An access floor system, comprising:
a floor panel; and
a support structure supporting the floor panel,
wherein the floor panel includes multiple unit panels, and
the support structure includes:
a plurality of first beam elements disposed in a first direction;
a plurality of second beam elements disposed in a second direction perpendicular to the first direction;
a post supporting at least part of the plurality of first beam elements and the plurality of second beam elements; and
a plurality of pedestals seated on top of the plurality of first beam elements and the plurality of second beam elements, and supporting the floor panel,
wherein each of the plurality of pedestals seats on top of a pair of first beam elements and a pair of second beam elements,
wherein the pedestal includes:
a base portion comprising four base assemblies and four pedestal connection members;
a head portion supporting the floor panel; and
a connection portion inserted into the base portion and the head portion, wherein the connection portion is a height-adjustable thread,
wherein each of the four pedestal connection members connects the base portion with each of the pair of the first beam elements and the pair of the second beam elements by passing through each of the four base assemblies.
10. The support structure of claim 9 , wherein the base assembly includes:
a base nut with an opening, formed in the base portion; and
a base bolt rotatably coupled to the base nuts, wherein
the base bolt includes a slot formed therein.
11. The support structure of claim 10 , wherein the first beam element includes a first upper hole,
the second beam element includes a second upper hole, and
the pedestal connection members is inserted into the first upper hole or second upper hole by passing through the slot and the base nut.
12. The support structure of claim 10 , wherein the slot includes an opening linearly extending on the base bolt, and
the pedestal connection members is received in the slot such that the pedestal is movable within a range defined by a length of the openings of the slot, whereby the pedestal is movably seated on the top of the pair of first beam elements and the pair of second beam elements.
